Abstract
The utility model discloses a vacuum generator, which comprises a cylinder and an end cover mounted at one end of the cylinder. An air passage is arranged in the end cover, a high-pressure nozzle is fixedly mounted on the inner side of the end cover, an inner air pore of the high-pressure nozzle is communicated with the air passage on the end cover, and a center line of the air pore is parallel to a center line of the cylinder. The vacuum generator is simple in structure and low in cost, vacuum air flow is increased greatly, discharging effect of tipping paper can be improved effectively, rub-connecting quality and effective equipment operating rate are improved, scrappage is reduced, production loss is reduced, and production cost is saved.
Description
Technical field
The utility model belongs to the cigarette machine technical field, particularly a kind of negative pressure generator.
Background technology
Negative pressure generator is one and sprayed by pressure-air and produce means for applying negative, and different according to the gap of the pressure of pressure-air and flow and injection place, newly the vacuum magnitude and the direction of generation are also inequality.
Prop up in the cigarette process at the tobacco business cigarette, utilize negative pressure generator to blow the yew scraps of paper.But, the negative pressure generator that uses in the rolling up and connecting machine at present, the hole that its pressure-air that produces negative pressure is 2.5mm by 8 diameters that are distributed on the end face circumference provides; The negative pressure flow that negative pressure generator produces is not enough; The discharge effect of the yew scraps of paper is undesirable, and the unnecessary yew scraps of paper are easy to paste on the rubbing drum, influences rubbing quality and equipment effective operation efficient; Cause waste product to increase, the production loss is big.
The utility model content
The purpose of the utility model provides the negative pressure generator that a kind of simple in structure, negative-pressure air-flow amount is big, equipment effective operation rate is high.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of negative pressure generator; Comprise cylindrical shell and the end cap that is installed in cylindrical shell one end, be provided with air flue in the said end cap, the end cap inboard is installed with high pressure nozzle; Pore in the high pressure nozzle is connected with air flue on the end cap, and the pore center line is parallel with the cylindrical shell center line.
Said high pressure nozzle outer end is taper.
Compared with prior art, the utility model has the advantages that: the utility model comprises cylindrical shell and the end cap that is installed in cylindrical shell one end, is provided with air flue in the said end cap, and the end cap inboard is installed with high pressure nozzle; Pore on the high pressure nozzle is connected with air flue on the end cap, and it is simple in structure, and is with low cost; Improve the negative-pressure air-flow amount greatly, can effectively improve the discharge effect of the yew scraps of paper, improved rubbing quality and equipment effective operation rate; The rate of reducing the number of rejects and seconds reduces the production loss, saves production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of end cap among Fig. 1.
The specific embodiment
Like Fig. 1, negative pressure generator shown in Figure 2; It comprises cylindrical shell 1 and the end cap 2 that is installed in cylindrical shell 1 one ends; In end cap, be provided with air flue 3, end cap 2 is provided with end cap fixing hole 6 and high pressure nozzle fixing hole 7, and end cap 2 is fixedly mounted on cylindrical shell 1 end through end cap fixing hole 6.Be installed with high pressure nozzle 4 in end cap 2 inboards through high pressure nozzle fixing hole 7, the outer end of high pressure nozzle 4 is convex cone shaped, and the pore 5 in the high pressure nozzle 4 is connected with air flue 3 on the end cap 2, and the center line of pore 5 is parallel with the center line of cylindrical shell 1.
The utility model course of work is: pressure-air gets into nozzle 4 by end face 2 outsides via air flue 3, through air passing hole 5 ejections, is used to blow the yew scraps of paper then.
When the utility model was used for rolling up and connecting machine, its negative-pressure air-flow direction was parallel to the drum axis, and the negative-pressure air-flow amount can make the yew scraps of paper that break away from wheel body discharge along set direction, thereby did not influence other mechanism's operate as normal.
Claims (2)
1. negative pressure generator; Comprise cylindrical shell and the end cap that is installed in cylindrical shell one end, it is characterized in that: be provided with air flue in the said end cap, the end cap inboard is installed with high pressure nozzle; Pore in the high pressure nozzle is connected with air flue on the end cap, and the pore center line is parallel with the cylindrical shell center line.
2. negative pressure generator as claimed in claim 1 is characterized in that: said high pressure nozzle outer end is taper.
